IM PROVEM ENT IN STRAW-CUTTERS.

Specification forming part of Letters Patent No. 213,253, dated March 11, 1879; application filed August 3, 1878.

To all whom it may concern;

Be it known that I, THOMAS B. SHAW, of Thompson, in the county of Fulton and State of Pennsylvania, have invented a new and valuable Improvement in Straw-Gutters; and I do hereby declare that the following is afull, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawings, making a part of this specification, and to the letters and figures of reference marked thereon.

Figure 1 of the drawings is a representation of a front view of my straw-cutter. Fig. 2 is a top-plan view of the same, and Fig. 3 is a view of a side elevation.

The nature of my invention consists in the construction and arrangement of a straw-cutter, as will be hereinafter more fully set forth.

The annexed drawings, to which reference is made, fully illustrate my invention.

A represents the cutter-box, supported at its rear end by a leg, B, and at its front end by a vertical frame, G, provided at its bottom with a suitable sill, G, to make the machine stand steady.

At the front end of the cutter-box, in grooves in the side pieces of the frame, are placed two verticallysliding frames or gates, D D, to which the cutters F F, respectively, are secured. These cutters are made in V form, as shown, and placed in opposite directions, as shown.

The front gate or frame, D, is connected by a pin or screw, a, to a lever, G, which is pivoted to the front of the frame 0. The rear frame, D, is, by a rod, E, connected with a lower lever, G, pivoted at one end to the sill G. The two levers G G are connected by a rod or bar. H, as shown, so that by operating the upper lever, G, both the frames D D will be operated or moved vertically in opposite directions, and the straw be out by the knives F F from above and below at the same time.

In the. box A are arranged two feed-rollers, I I, one above the other, geared together by cog-Wheels J J on one side. At the other side is atoothed wheel, L, on the journal of the upper roller, and into this toothed wheel takes a pawl, 11, hinged to a lever, P, pivoted to the side of the box. This lever rests on a pin, m, and projects over the operating-lever G. At every upward stroke of this lever the lever P is lifted, and the pawl P rotates the upper roller a certain distance, and this rotates the lower roller, so as to feed the straw forward.

In a full-sized machine springs will be arranged to hold therollers down.

What I clann as new, and desire to secure by Letters Patent, is-

"The combination of the geared rollers I I, toothed wheel L, pivoted lever P, with pawl 10, and the operating-lever G, substantially as and for the purpose set forth.

In testimony that I claim the above I have hereunto subscribed my name in the presence of two witnesses.
